The object of this study is the process filtering astronomical frames that contain images objects in Solar System. In order to recognize image an contrast with background frame, it necessary filter image. It proposed use a modification median reduce dynamic range substrate. This will lead increase signal-to-noise ratio entire However, identified problem area each during distortion structure and artifacts. Therefore, solve problem, fast procedure has been eliminate them. A new technique for...

We present approaches to checking models of concurrent business processes based on analysis their behavior, which is represented trough event records processes. Recording and are made during managing These presented in the form traces, consist a sequence events. Every describes state process after finishing one its activities. have developed an approach constructing traces from single trace, consisting events various processes, by taking into account links between resources sequential This...

The appearance of "blurred" digital images is a consequence the violation immobility camera during shooting objects under study. To this end, procedure was devised for matched filtering blurred image object using its typical form in series frames. This based on automated formation image, as well choice special parameters transfer function filter. Adapting specifically to makes it possible perform more accurate assessment required compared analytically set profile. take into account features...

The model of the event log information system has been improved. contains sequences events consistent with implemented management actions within both process approach and functional approach. A strict linear order in time was assigned for each pair belonging to same process. is designed describe prototype as-is business process.A case-based a process, describing features its known implementations, reflected log, proposed. combines set operations takes into consideration implement these...

The main purpose of modern information systems (IS) is to support the procedures controlling many business processes (BP) an enterprise. At same time, due a weak formalization BP, development, reengineering various service-oriented IS and IT services are complex problem. To address this problem, task improve method for choosing that meet assigned set functional non-functional limitations was stated. specific features original were analyzed, its shortcomings identified. model BP precedent...

At the moment, use of cloud technology is increasingly used in various areas human activity. Creating a virtual private no longer big problem and practice more often. same time, distance learning systems online courses master classes are becoming popular.With help technologies it possible to organize modern university. This solution perfect for part-time students, evening students full-time who reasons can not attend classes. Conventionally, be divided into server client parts.

A feature of irregular end-to-end business processes is that at some competitive points their number can not only change, but a new process be included in number. Given these features, problems arise planning, accounting, control, analysis and regulation. To solve them, methods tools operational calendar planning are used. However, when managing such competing for shared resources. the article proposes generalized algorithm finding solution to establish priorities launching with...

The problem of managing many end-to-end business processes is related to the distribution common enterprise resources between them. This leads delays in their implementation due insufficient resources. result such can be a failure complete as whole, which lead significant material financial losses. management process consists pausing or starting execution new based on formalized experience presented form precedents. main operational timeliness development mathematical models. It proposed use...
